Titration of Chemical Oxygen Demand

Analysis outlining the method for the quantitative determination of the chemical oxygen demand COD according to DIN 38 409, part 41, above concentration of 15 mg/l. The analysis was performed on the Schott Instruments TitroLine 7000 Advanced Titrator with wireless sensor recognition for exclusion of erroneous measurements. Note: After use, the Pt 61 electrode should be placed in KCl 3 mol/l immediately to make sure that there is always sufficient electrolyte solution in the electrode.
